introduce the auto_reset_crashkernel option to kdump.conf
This option will determine whether to reset kernel crashkernel
to new default value or not when kexec-tools updates the default
crashkernel value and existing kernels using the old default kernel
crashkernel value. Default to yes.

rewrite reset_crashkernel to support fadump and to used by RPM scriptlet
Rewrite kdumpctl reset-crashkernel KERNEL_PATH as
kdumpctl reset-crashkernel [--fadump=[on|off|nocma]] [--kernel=path_to_kernel] [--reboot]
This interface would reset a specific kernel to the default crashkernel value
given the kernel path. And it also supports grubby's syntax so there are the
following special cases,
- if --kernel not specified,
- use KDUMP_KERNELVER if it's defined in /etc/sysconfig/kdump
- otherwise use current running kernel, i.e. `uname -r`
- if --kernel=DEFAULT, the default boot kernel is chosen
- if --kernel=ALL, all kernels would have its crashkernel reset to the
default value and the /etc/default/grub is updated as well
--fadump=[on|off|nocma] toggles fadump on/off for the kernel provided
in KERNEL_PATH. If --fadump is omitted, the dump mode is determined by
parsing the kernel command line for the kernel(s) to update.
CoreOS/Atomic/Silverblue needs to be treated as a special case because,
- "rpm-ostree kargs" is used to manage kernel command line parameters
so --kernel doesn't make sense and there is no need to find current
running kernel
- "rpm-ostree kargs" itself would prompt the user to reboot the system
after modify the kernel command line parameter
- POWER is not supported so we can assume the dump mode is always kdump
This interface will also be called by kexec-tools RPM scriptlets [1]
to reset crashkernel.
Note the support of crashkenrel.default is dropped.

commit 945cbbd59b
Author: Coiby Xu <coxu@redhat.com>
Date: Tue Dec 7 15:16:07 2021 +0800
add helper functions to get kernel path by kernel release and the path of current running kernel
grubby --info=kernel-path or --add-kernel=kernel-path accepts a kernel
path (e.g. /boot/vmlinuz-5.14.14-200.fc34.x86_64) instead of kernel release
(e.g 5.14.14-200.fc34.x86_64). So we need to know the kernel path given
a kernel release. Although for Fedora/RHEL, the kernel path is
"/boot/vmlinuz-<KERNEL_RELEASE>", a path kernel could also be
/boot/<machine-id>/<KERNEL_RELEASE>/vmlinuz. So the most reliable way to
find the kernel path given a kernel release is to use "grubby --info".
For osbuild, a kernel path may not yet exist but it's valid for
"grubby --update-kernel=KERNEL_PATH". For example, "grubby -info" may
output something as follows,
index=0
kernel="/var/cache/osbuild-worker/osbuild-store/tmp/tmp2prywdy5object/tree/boot/vmlinuz-5.15.10-100.fc34.x86_64"
args="ro no_timer_check net.ifnames=0 console=tty1 console=ttyS0,115200n8"
root="UUID=76a22bf4-f153-4541-b6c7-0332c0dfaeac"
initrd="/var/cache/osbuild-worker/osbuild-store/tmp/tmp2prywdy5object/tree/boot/initramfs-5.15.10-100.fc34.x86_64.img"
There is no need to check if path like
/var/cache/osbuild-worker/osbuild-store/tmp/tmp2prywdy5object/tree/boot/vmlinuz-5.15.10-100.fc34.x86_64
physically exists.
Note these helper functions doesn't support CoreOS/Atomic/Silverblue
since grubby isn't used by them.

ppc64/ppc64le: drop cpu online rule in 40-redhat.rules in kdump initramfs
Onlining secondary cpus breaks kdump completely on KVM on Power hosts
Though we use maxcpus=1 by default but 40-redhat.rules will bring up all
possible cpus by default.
Thus before we get the kernel fix and the systemd rule fix let's remove
the cpu rule in 40-redhat.rules for ppc64/ppc64le kdump initramfs.

kdump-lib.sh: fix variable quoting issue
Fixed quoting issues found by shellcheck, no feature
change. This should fix many errors when there is space
in any shell variables.
And fixed how remove_cmdline_param is being called in prepare_cmdline.
Kernel parameters can have space like: param="spaces in here". So currently
remove_cmdline_param is broken since its args always get split by space.
But prepare_cmdline is expecting remove_cmdline_param to split its args
by space and passing a list of kernel args separated by space as a whole arg.
So fix that by using `xargs` to parse and split the args properly, then
call remove_cmdline_param.
Following quoting related issues are fixed (check the link
for example code and what could go wrong):

kdump-lib.sh: rework nmcli related functions
This fixes word splitting issue with nmcli args. Current kexec-tools
scripts won't call nmcli with correct arguments when there are space in
network interface name.
nmcli expects multiple parameters, but get_nmcli_value_by_field only
accepts two params and depends on shell word splitting to split the
_nm_show_cmd into multiple params, which is very fragile.
So switch the param order, simplified this function and now multiple
params can be used properly.
And get_nmcli_connection_show_cmd_by_ifname returns multiple
nmcli params in a single variable, it depend on shell word splitting to
split the words when calling nmcli. But this is very fragile and break
easily when there are any special character in the connection path.
This function is only introduced to get and cache the nmcli command
which contains the "connection name".
Actually only cache the "connection path" is enough. Callers should
just call get_nmcli_connection_apath_by_ifname to cache the path, and
a new helper get_nmcli_field_by_conpath is introduced here to get value
from nmcli. This way "connection path" can contain any character.
Also get rid of another nmcli_cmd usage in
get_nmcli_connection_apath_by_ifname which stores multiple params in a
single bash variable separated by space.

kdump-lib.sh: replace '[ ]' with '[[ ]]' and get rid of legacy ``
Updated file syntax with following command:
sed -i -e 's/\(\s\)\[\s\([^]]*\)\s\]/\1\[\[\ \2 \]\]/g' kdump-lib.sh
(replace '[ ]' with '[[ ]]')
sed -i -e 's/`\([^`]*\)`/\$(\1)/g' kdump-lib.sh
(replace `...` with $(...))
And manually updated [[ ... -a ... ]] and [[ ... -o ... ]] with && and
||.

kdump-lib-initramfs.sh: make it POSIX compatible
POSIX doesn't support keyword local, so add double underscore and prefix
to variable names, and reduce variable usage, to avoid any variable name
conflict.
Also reformat the code with `shfmt -s -w kdump-lib-initramfs.sh`.

dracut-kdump.sh: make it POSIX compatible
POSIX doesn't support keyword `local`, so this commit reduced variable usage.
Heredoc ("<<<") operation is also not supported, so kdump.conf is now pre-parse
into a temp file. Also fixes many POSIX syntax errors.
